In the vein of considering tools for jobs...
Is Perl actually the right job for doing this? I know that:
sort <file> | uniq
gives a pretty good sort speed.
The logs I deal with here are hundreds of megs long (or several gigs in many cases), and I have to deal with an awful lot of them.
It works fine for me.. I know it's not Perl, but, it's a tool that does the job adequately for a lot of things..
Just a thought,
Malk.
Update:
For a set of windows tools (only just noticed you were using that), try
this.
